To all whom timer concern:

Harman HA'n'rLrsn and Fnmnmorr. Lmn, citizens of the United States,and'residents of St. Louis, Missouri,

jhave'invented certain' new and useful In provements in E -Turners forIncubators,

of which the i0 owing is aspecification containing t't'iiull, clear, andexact description, reference being had to the accompanyingdrawings,-form1ng a part hereof,

-.()ur invent1on relates'to an'egg turner for to construct asimple;1inexpensive eggho ding tray such as-is ordinarily'used inincubators, and to ,15

bator with the front door thereof swung open, and showing eg traystherein equipped with our improve turning means; a portion of one of theegg trays being shown in vertical section; Fig. 2 is a plan view of oneofthe trays with a portion of the apron broken away; Fig. 3 is a sectiontaken on the line 3-3 of Fig. 2; and, Fig. 4 is a detail section takenon the line 4-4 of Fig. 2.

Referring lgy numerals to the accompanying drawing: 1 esignates arectangular frame, preferably constructed of wood,and of such .size asto readil fit on the supporting rails within the incu ator, and fixedagainst the inner faces and lower portions of the-front and rear-railsofthis frame 1 -is a pdir of strips 2, in the top of one of which isformed, at suitable distances apart, notches 3, there being recessesformed in the ,o posite strip 2, which notches and recesses lorinbearings for trunnions 4 formed on or carried by th ends of a series oftransyersely disgosed rollers 5.

no of the trunnions fi of each end rolldr extends thr ughthecorresponding strip 2 'and the odor end of said trunnion is madenoncirculanas designated by7, in brdento receive a key, as shown bydotted lines in Fig. 4,.whi'ch' key is for. the purpose of ro- 'tatl',said end'rollers. V Y

8 esignates an apron'of cloth orjanal ogous flexible material, the endsof which are fixed in any suitable manner to the two end rollers 5, andsaid apron .isYof ,such- 6G. length or of such-fullness as thatdepressions or pockets are formed between the rollers 5, whichdepressions are occupiedby the rows} 0 e so that when the o positeenrollerjis rotated by means of t e key, a corresponding amount of theapron will be wound upon said op osite roller, and that portion of theapron ying upon and between the intermediate rollers will be shifted insuch a, manner as thatthe. eggs carried u on said apron will be rotatedapproximate y: a half turn, thus ing all of said eggs.

By our nnproved arrangement and con .struction it isnot necessary totouch the eggs:

with the hands during the turning operation,

and as the apron is constructed of cloth or .80

analogous material the'eggs are maintained upon a comparatively softsurface, and therefore the dangtr of breakage during the turningoperation is reduced to a minimum.

A tray and. turnin device of our improved construction is app icable forall forms of incubators, and can also be advantageously used in eggcasesand the like, where eggs are packed for storage, and where it isnecessary to turn the eggs at certain intervals.

We claim: y
